alpha2-macroglobulin, MAM, A2M, alpha2M
Alpha-2-macroglobulin is a protease inhibitor and cytokine transporter. It inhibits many proteases, including trypsin, thrombin and collagenase. A2M is implicated in Alzheimer disease (AD) due to its ability to mediate the clearance and degradation of A-beta, the major component of beta-amyloid deposits.

Glaser et al., Stockholm, Sweden. In Biochim Biophys Acta, 18 Mar 2014

MAM (mitochondria-associated membranes) in mammalian cells: Lipids and beyond.
Vance, Edmonton, Canada. In Biochim Biophys Acta, Jan 2014
UNLABELLED: One mechanism by which communication between the endoplasmic reticulum (ER) and mitochondria is achieved is by close juxtaposition between these organelles via mitochondria-associated membranes (MAM).
Progressive Brain Damage, Synaptic Reorganization and NMDA Activation in a Model of Epileptogenic Cortical Dysplasia.
Battaglia et al., Milano, Italy. In Plos One, Dec 2013
We previously demonstrated in a rat model of acquired focal cortical dysplasia, the methylazoxymethanol/pilocarpine - MAM/pilocarpine - rats, that the occurrence of status epilepticus (SE) and subsequent seizures fostered a pathologic process capable of modifying the morphology of cortical pyramidal neurons and NMDA receptor expression/localization.
Intrinsic epileptogenicity of dysplastic cortex: converging data from experimental models and human patients.
Nobili et al., Milano, Italy. In Epilepsia, Sep 2013
To investigate cellular and molecular bases of epileptogenic mechanisms and possible effect of severe epilepsy on the malformed cortex we have here performed a parallel analysis of a rat model of acquired cortical dysplasia previously established in our laboratory, i.e., the methylazoxymethanol/pilocarpine (MAM-PILO) rats, and surgical samples from patients with type IIB FCD.
Diet1 functions in the FGF15/19 enterohepatic signaling axis to modulate bile acid and lipid levels.
Reue et al., Los Angeles, United States. In Cell Metab, Jul 2013
Diet1 encodes a 236 kD protein consisting of tandem low-density lipoprotein receptor and MAM (meprin-A5-protein tyrosine phosphatase mu) domains and is expressed in the enterocytes of the small intestine.
[Variability of healthy human proteome].
Larina et al., In Biomed Khim, 2012
On the contrary, proteins and peptides characterized by insignificant dispersion in healthy population (such as albumin--coefficient of variation (CV) 9%; transferrin--CV14%; C3c complement--CV 17%, alpha-1 acid glycoprotein--CV 21%, alpha2-macroglobulin--CV 20%; transthyretin fragment--CV 28,3% and beta-chain alpha2-HS-glycoprotein--CV 29,7%) can provide us with important information about state of health.

Requirements for mediator complex subunits distinguish three classes of notch target genes at the Drosophila wing margin.
Treisman et al., New York City, United States. In Dev Dyn, 2011
Genes activated by Notch signaling at the dorsal-ventral boundary of wing disc fall into classes affected differently by the loss of kinase module subunits. The distinctions do not result from different requirements for Groucho.

Peak serum levels of alpha(2)-macroglobulin and alpha(1)-acid glycoprotein injected at 0.05 mL/rat were significantly lower than those at 0.2 or 0.4 mL/rat. No significant differences were observed for peak serum levels at 0.2 and 0.4 mL/rat.
Sigma-1 receptor chaperones at the ER-mitochondrion interface regulate Ca(2+) signaling and cell survival.
Su et al., Baltimore, United States. In Cell, 2007
The ER supplies Ca(2+) directly to mitochondria via inositol 1,4,5-trisphosphate receptors (IP3Rs) at close contacts between the two organelles referred to as mitochondrion-associated ER membrane (MAM).
The Notch transcription activation complex makes its move.
Kopan et al., Baltimore, United States. In Cell, 2006
